NCIS Video

Forensic Science Test

20 multiple choice questions.

The students presented their case and identified the suspect. 

Each student had to complete a brief summary that included the name of the suspect and the evidence used in coming to a conclusion.

The students also completed a test review for the forensic science test scheduled for Thursday 5/16.

The students started their final crime scene analysis.

They will review the suspect list, the witness statements, and the forensic evidence.

The students will be responsible for “solving” the crime by indentifying a suspect and presenting the evidence used to make their conclusion.

The students will investigate a mock crime scene.

They will be responsible for collecting and documenting evidence. 

Each student will take notes regarding the location of all the evidence.

Each student will sketch the crime scene.

We watched an episode of NCIS.  The episode involved DNA testing, firearms and ballistics testing, and trace evidence analysis.

The students completed a firearms and ballistics lab.

They matched shell casings from a suspects home to the shell casings collected from a crime scene.

They compared the sizes of various caliber casings and the firing pen marks left by the varied weapons.

The students completed the forensic lab investigations that were started on Tuesday, 5/8.

They also completed an additional blood analysis lab.

The students completed two lab investigations that matched evidence with matter taken from suspects.

The idea was to use microscopes to analyze matter that was collected from a crime scene against evidence collected from suspects.

The students analyzed lipstick, nail polish, hair, and clothing fibers.

Eyewitness

Eyewitness information to a crime is not always accurate. 

An eyewitness account is reliant on the length of time of the crime.

The mental and health condition of the witness.

The time of the day that the crime occurred.

There are multiple cases in which the eyewitness was incorrect regarding the identification of a suspect.
